[Go] Expose spf13/cobra commands via HTTP poc (do not do this at home)

This poc tries to demonstrate how "easy" can be exposing CLI tools via HTTP API. The example isn't perfect. It doesn't provide a REST API but it just allow to quickly prototype tooling that can be accessible both via CLI or HTTP.

This is a do not do this at home, however it can be used as starting point for interesting approaches.

A bit of context

I decided to do this insane proof of concept in order to (in)validate the idea of exposing cobra commands via HTTP as a quick prototyping framework. Once built, you just need to create commands and the api will expose them. Even though it could be fast for prototyping, this is not the ideal solution as it's super tricky.

Where foo/bar is the new dir where your files will be placed.

• Enable the tracer on your xdebug.ini file (see the xdebug.ini file).
• If you are gonna trace an http request, make sure your xdebug.trace_output_dir is writable by the webserver user (www-data).
• Execute your script or your request. You can use produce_segmentation.php to test.
• See the trace file(s) on your xdebug.trace_output_dir.
